(Cl. l46-102) The present invention relates to slicing ma- On one side of the base 1 is mounted a guide chines and more particularly to the guides which which has a substantially V-shaped groove in support the reciprocating carriage found in the which the rollers 16 are adapted to travel. These type of machine illustrated herein and has for rollers are mounted to rotate on the spindles 21 5 one of its objects the provision of means for comsecured to the bracket 22 on the carriage 2 and pensating for wear in the guiding means. carry a portion of the weight of the carriage as Another object of this invention is to provide it reciprocates. Another guide 25 is mounted on means whereby both the vertical movement of the opposite side of the base member and a roller the carriage and the horizontal movement there- 24 rotatably mounted on the bracket 23 is adapt- 10 of, transversely to the guides, is, in a large ed to co-operate with this guide to help support measure, prevented. the carriage.

Another object of this invention is to provide To keep the carriage from vertical movement,

The carriage has a cross guide 15 in Fig. 1. The rollers 29 and 30 are roslide 3 W upstanding brackets 4 adapted to tatably mounted upon pins 28 mounted in the pp the Clamping bar y means of bearings bracket 27 corresponding to the bracket 22 shown 5 and 6 mounted on the upstand members in Figs. 1 and 2.

The rotation of the shaft 13' also 32 performs the same function as the guide 15 causes the reciprocation of the carriage 2 in a in Figs. 1 and 2. Rollers 35 each have a hub porwell-known manner such as by a crank and pittion 37 and an outer rim portion 36 between which man Co ect o d ve y gears connected to the are interposed a row of ball bearings to provide shaft 13'. for a better operation of the rollers 35. These rollers are mounted on the bolts 39 which clamp the hub portion 37 against the bracket 31' on the carriage 31. The yieldingly pressed roller 42 is rotatably mounted on the lever 41 pivoted at 40 to the bracket 31'. The opposite end of the lever has a recessed portion 43 opposing a similar recessed member-44 on the bracket 31 and a spring 45 is placed with its opposite ends in the said recessed portions so that the roller 42 is yieldingly urged upward against the upper guiding surface 34 and this tends to re-act and hold the rollers 35 against the lower bearing surface 33.

In Figs. 1 to 5, inclusive, the arrangement in each of the modifications comprises a guide with two supporting rollers and a yieldingly pressed roller for co-operation with the guide to prevent vertical and lateral movement of the carriage. A second guide, such as 25, shown in Fig. 2, cooperates with a roller such as 24 to support the opposite side of the carriage.

Obviously, those skilled in the art may make various changes in the details and arrangement of parts without departing from the spirit and scope of the invention as defined by the claims hereto appended, and I therefore do not wish to be restricted to the precise construction herein disclosed.

Having thus fully described and shown an embodiment of my invention, what I claim and desire to secure by Letters Patent of the United States is:-

-1. A slicing machine comprising a support, a carriage, a one-piece U-shaped guide on said support, a groove in one arm of the U-shaped memher, a roller on said carriage adapted to co-operate with the groove, and yielding means for maintaining said roller in said groove, said yielding means comprising a second roller rotatably mounted on a pivoted lever on said carriage and a spring for urging said lever in a direction to bring the second roller into engagement with the opposite arm of the U-shaped guide.

2. A slicing machine comprising a support, a carriage, a U-shaped guide on said support, a groove in one arm of said U-shaped member, an antifriction roller on said carriage adapted to cooperate with said groove, and yielding means for maintaining said antifriction roller in said groove, said yielding means comprising a second roller rotatably mounted on a pivotal lever on said carriage, and a spring for urging said lever in a direction to bring the second-roller into engagement with the opposite arm of the U-shaped guide.

3. A slicing machine comprising a support, a carriage, a one-piece U-shaped guide on said support, a groove in one arm of the U-shaped memher, a roller on said carriage adapted to cooperate with the groove, and yielding means for maintaining said roller in said groove, said yielding means comprising a roller mounted on a fiat spring for engaging the opposite arm of the U-shaped guide, and said groove and roller having their cooperating surfaces substantially V-shaped in cross section.
